Saying Hello to the High!

Well it finally felt like summer today...for a while...sort of. Okay, the daytime was still slightly off the seasonal average (27) but 26 was not bad and with the Humidex it felt closer to 29. So what's with the warm-up? Well on Friday we were talking about the lack of a Bermuda High on the weather map contributing to a cooler than normal summer and we're finally seeing that high develop. A Bermuda High is a semi-permanent feature that pushes warm, moist air into the region contributing to our normally hot and humid summers. This feature's clockwise rotation kicks in warm tropical air (mTw) during the summer months. In contrast, its west coast cousin (the Pacific High) does the opposite for the Pacific coast. (The high's clockwise rotation in this case pulls in cool air from the north [mPk] keeping west coast summers cooler and less humid). So does the "better late than never" appearence of the Bermuda High mean we'll finally see a warmer summer? Well...maybe. It is only a contributing factor but it's appearance isn't going to hurt.
